  • In July the first 250 kWh a month cost 35.2¢ each; then 37.8¢ above 250 kWh a month.
  • An average New York home (784 kWh in July) goes past the first tier, so extra load such as an EV is priced higher.
  • Fixed charge: $23.91 a month.

SC-1 Rate III: Voluntary Time-of-Day, New York City

  • Mid-peak 8 am–2 pm, Peak 2 pm–6 pm, Mid-peak 6 pm–12 am on July weekdays; 4 of 24 hours carry the top price of 122.9¢.
  • The cheapest July weekday hour costs 15.4¢, so moving 1 kWh out of the top hours saves 107.5¢.
  • January weekdays range from 18.6¢ to 31.9¢.
  • Weekends differ: Mid-peak 8 am–12 am.
  • Fixed charge: $23.91 a month.
